Although natural disasters are caused by nature and there is nothing that we can do to prevent them happening, there are many different natural causes that lead to natural disasters, and being aware of these causes enables us to be better prepared when such disasters do arrive. One common natural disaster is flooding, which occurs when a river bursts its banks and the water spills out onto the floodplain.
This is far more likely to happen when there is a great deal of heavy rain, so during very wet periods, flood warnings are often put in place. There are other risk factors for flooding too: Drainage basins of impermeable rock also cause the water to run faster over the surface. Earthquakes are another common natural disaster that can cause many fatalities.
These plates do not always move smoothly and can get stuck, causing a build-up of pressure. Tell them that often there is nothing that can be done to prevent them and no one is to blame for them as they are purely acts of nature that we cannot control.
Your natural disasters essay will be much easier to write if you take the time to map out your outline first. Your outline allows you to understand what the structure of your essay will be and what subjects you should cover within each section.
Like a map, it helps you to get to your destination quickly without getting lost. A simple outline can save you a huge amount of time within the writing process and will often make your essay far more cohesive as well as easier to write. Start with what you want to cover within each of the three main sections, we have already discussed your introduction. The main body should cover a number of different types of natural disasters, you should write a full paragraph describing the causes and effects of each so that the reader can gain a full appreciation for the power of nature and how small we are when compared to it.
This is only a very small fraction of the major natural disasters that have affected mankind within the last century. There have been natural disasters that have occurred in every country on every continent in the world that you could write about for your natural disasters essay.
Your summary should sum up all of these disasters and you should then make some personal comments about how we could prevent harm from some of these in the future or even suggest disasters that may have a bigger impact on us in the future.
The Texas Hurricane Harvey may be a disaster that is recent but it far from the worst that has affected people in recent years. The Indian Ocean tsunami in killed almost thousand people while in a cyclone in what is now Bangladesh killed as many as half a million people. From storms and floods to volcanoes and earthquakes, there are many things that could affect us with little or no warning. Writing about these disasters however, will require research and careful planning if you are going to get the results that you need with your writing.
We have been providing our clients with support for many years and can offer you all of the help and advice that you may need to write your essays to a standard that is going to help you to get the grades that you need. Writing an essay on natural disasters does not have to be difficult if you take the time to get your research done and to plan out your writing. The following will help you to ensure that you will write an essay that is going to be attention-grabbing and grade winning:.
The area vulnerable to floods is 40 million hectares and the average area affected by floods annually is about 8 million hectares. About 30 million people are affected by flood every year. Floods in the Indo-Gangetic-Brahmaputra plains are an annual feature. Drought prone areas comprise About 50 million people are affected annually by drought. Of approximately 90 million hectares of rain-fed areas, about 40 million hectares are prone to scanty or no rain. Of these, the majority has their initial genesis over the Bay of Bengal and strike the east coast of India.
On an average, five to six tropical cyclones form every year, of which two or three could be severe. An analysis of the frequency of cyclones on the East and West Coasts of India between and shows that nearly cyclones occurred 92 severe in a 50 km wide strip on the East Coast.
Less severe cyclonic activity has been noticed on the West Coast, with 33 cyclones occurring in the same period, out of which 19 of these were severe. The cyclones of severe intensity and frequency in the north Indian Ocean are bi-modal in character, with their primary peak in November and secondary peak in May.
The disaster potential is particularly high at the time of landfall in the north Indian Ocean Bay of Bengal and the Arabian Sea due to the accompanying destructive wind, storm surges and torrential rainfall. Of these, storm surges are the greatest killers of a cyclone, by which sea water inundates low lying areas of coastal regions and causes heavy floods, erodes beaches and embankments, destroys vegetation and reduces soil fertility.
In the hilly terrain of India including the Himalayas, landslides have been a major and widely spread natural disasters that often strike life and property and occupy a position of major concern.
One of the worst tragedies took place at Malpa Uttrakhand on 11th and 17th August, When nearly people were killed when massive landslides washed away the entire village. This included 60 pilgrims going to Lake. In Cloud burst led flash mudslides and flash floods killed people, including 6 foreigners and injured more than and swept away number of houses, sweeping away buildings, bus stand and military installations in trans-Himalaya Leh town of Jammu and Kashmir.
Giving due consideration to the severity of the problem various land reform measures have been initiated as mitigation measures. Avalanches are river like speedy flow of snow or ice descending from the mountain tops. Avalanches are very damaging and cause huge loss to life and property. Beside killing people, avalanches also damage the roads and others properties and settlements falling in its way.
Tsunami, or seismic sea waves, are large ocean waves generated by impulses from geophysical events occurring on the ocean floor or along the coastline, such as earthquakes, landslides and volcanic eruptions.
Mostly occurring in the Pacific Ocean, tsunamis, although hardly noticeable at sea, can reach gigantic proportions as they reach shallow, coastal waters. In Hawaii and Japan, for example, tsunamis have been known to reach 30 m in height. At least 22 countries along the rim of the Pacific are estimated to beat risk from potential tsunami.
The fact that tsunamis can travel 10, km at velocities exceeding km per hour with little loss of energy and are, therefore, capable of hitting areas not directly affected by the inducing event, has led to the establishment of a tsunami early warning service for the whole circum-Pacific area. However, only a few of the 22 countries most at risk are considered to have standard operating procedures for immediate evacuation or reliable, rapid communication systems capable of receiving real-time warnings from the Pacific Tsunami Warning Centre.
About 6,people have been killed by tsunami during alone. Probably the best documented of these events is the occurrence at Noshiro, Japan, in which caused approximately deaths and extensive property damage and flooding. Tsunamis have multiple origin— Over past two thousand years there have been 10, 00, deaths attributed to tsunami in the Pacific region alone.
Earlier Pacific Tsunami warning system was established for forecasting the event. Judged by the frequency with which they cause damage and by the surface area of the regions they strike, windstorms can be said to be the most significant of all natural hazards.
Windstorms influence precipitation systems floods and, most importantly, cause severe destruction to crops and properties. Today increasing attention is being paid to windstorms, particularly tropical cyclones as some scientists see their incidence as being a possible indicator of global climatic change and predict an increase in their frequency. Have tropical cyclone frequencies or their intensities increased with global changes throughout the last century?
However, global listings of disasters rarely include those which occur in small states such as island states, which in areas such as the Caribbean, Indian Ocean and South Pacific are particularly prone to tropical cyclones. This is because listings often set a criteria based on magnitude of impact with which small states cannot compete against larger countries.
However, the proportional impact upon small states is often far greater in terms of population, housing and economics. The impact of cyclones goes far beyond just deaths and building damage. In developing countries destruction of infrastructure and primary agriculture can lead to a decrease in exports and gross national product, while increasing the likelihood of forfeiture of international loan repayments. Contamination of water supplies and destruction of crops can also lead to disease and starvation.
Many mid-latitude cyclonic depressions can give rise to exceptionally heavy rain and widespread flooding and snow fall too. Dust storms are windstorms accompanied by suspended clay, silt materials, usually but not always without precipitation.
Average million tonnes of dust are entrained by winds each year. Severe windstorms with high level of flush rain often called thunderstorms associated with lightning, hail and tornadoes cause massive destruction of properties and also human lives through out the world.
Early warning and emergency relief operation are the major management activity. Forest or bush fire, though not causing much loss to human life, is a major hazard for forest cover in the country.
As per Forest Survey of India report, 50 per cent of the forest cover of the country is fire prone, out of which 6. Average annual physical loss due to forest fire in the country is estimated to worth Rs. The major loss due to forest fire is caused to the environment which gets adversely affected by this calamity. The degradation of climate, soil and water quality, loss of wildlife and its habitat, deterioration of human health, depletion of ozone layer, etc.
The coniferous forests in the Himalayan region are very susceptible to fire and every year there are one or more major fire incidences in these areas. The other parts of the country dominated by deciduous forest are also damaged by fire up to an extent.
It is worth mentioning that in India 90 per cent of the forest fires are man-made intentionally or unintentionally. There are two types of magma ejected out of volcanoes —silica poor materials, and silica rich materials. The silica poor volcanoes called basaltic volcanoes, while the silica rich volcanoes are andesitic volcanoes.
There are many hazardous phenomena produced directly or as secondary effects, by volcanic eruptions. In addition indirectly they are associated with earthquake and tsunami events. Volcanoes are visually one of the most spectacular natural hazardous to occur and probably most devastating in terms of loss of human life. The volcano likes Mt. St Helena, Krakatoa, and Mt, Pelee are significant because of either the enormity of the eruption or the resulting death tool.
Vesuvius eruption causes 2, death and burying of the Pompeii city.
- A natural disaster is an event caused by natural destructive factors, which can be further divided into either climatic disasters such as floods and tornados, or geological disasters such as earthquakes, which consequently lead to great physical damage or life loss (Bankoff, , 56).
Natural disasters essaysDebris is scattered for miles, houses are unrecognizable, tress are bent like wet noodles, and vehicles have been thrown like baseballs. This would be an aftermath of a natural disaster.
Your natural disasters essay will be much easier to write if you take the time to map out your outline first. Your outline allows you to understand what the structure of your essay will be and what subjects you should cover within each section.5/5. Natural disasters include cyclones, earthquakes, floods, drought (though these two are now being increasingly considered ‘man- made’ disasters) heat and cold waves, landslides, avalanches, flash floods, severe thunderstorms, hail, low .
One of the most common natural disasters, but also one of the most commonly forgotten, is wildfires. These take place in many different countries all over the world, particularly during the summer months, and can be caused by a range of different things. A natural disaster is a major adverse event resulting from natural processes of the Earth; examples include floods, tsunami, volcanic, earthquakes, tornadoes and other geologic processes.
